Unique Content for Your DOG Site
How about things like:
A wide variety of high-priced information and physical items?
A huge market – most web users are potential customers?
Products that people actually buy online (repeatedly) and spend BILLIONS of dollars per year doing so?
Devoted consumers more concerned with getting the best products rather than the cheapest prices?
Search volumes in the millions, with plenty of high volume longtail keywords, so you can get your piece of the market without fighting all the competition?
